A drip tray with magnets for attaching to the side of a fridge/kegerator.
I tried to keep the inside edges smooth with fillets to make cleaning easier. One thing I had about the metal ones is cleaning the corners so I tried to eliminate that with this one.
I printed it with PETG so it could be cleaned with hot water and not distort like PLA would.
Magnets are: 12.7mm (0.5") diameter 3.2mm (0.125") thickness
Add the magnets
I attached them with a small bit of epoxy on the magnet. It is a pretty tight fit so you don't need much.
